Nick Diaz certainly didn’t appear to be pleased with how the judges scored his UFC 183 bout with Anderson Silva, and now a post from the outspoken veteran is raising questions about his fighting future. Following his decision loss to Silva last weekend, Diaz said he thought he won the fight, and remained non-committal about whether he’ll fight again. Of course, anyone who has followed Diaz over the years knows that he’s walked away from fighting before, but in the end, returned for big bouts.

Well, recently the following picture and caption appeared on Diaz’s Instagram account. Could the “dunfighting” hashtag just mean that his camp / bout with Silva is over? Or is the 31 year-old fighter relaying that he’s hanging up the gloves?

All this speculation is occurring just days after it was revealed that Diaz tested positive for marijuana metabolites following UFC 183. Since Diaz has tested positive for marijuana before, the star could be facing a lengthy suspension and fine from the Nevada Commission.

Love my people #mma #lodi #dunfighting
